CASTING MECHANISM FOR LlNOTYPE-MACHlNES;

SPECIFICATION forming part of Letters Patent No. 645,472, dated March13, 1900. Application filed September 9, 1899. Serial No. 729,966. (Nomodel.)

T to whom it may concern:

Be it known that 1, CHARLES HoLL1wnLL,of Broadheath, in the county ofChester, England, have invented certain new and useful Improvements inthe Casting Mechanism of Linotype-Machines; and I do hereby declarements in the casting :mechanism of the Merge'nthaler linotype-machinewhich is fully described in the specification of Letters Patent No.436,532, dated September 16, 1890, and in Patent No. 557,000, datedMarch 24, 1896. This machine can present its mold and cast many timesfrom one composed line of matrices while the operator is composing thenext line.

The object of the present invention is to make the said machine capableof automatically duplicating its production from one line of matricesand space-bars in order that two printing-machines may be kept suppliedsimultaneously with linotypes of the same matter, so that such a job asa pamphlet, that is wanted in the shortest possible time, may

be divided between two printing-machines and worked off in half the timethat one of them could do it in.

In the machine above mentioned the operator puts each composed line ofmatrices and space-bars within the grasp of a shifter (marked L L in thespecification above mentioned) andwhich-transfers it horizontally to amember known as a yoke or transporter or first elevator N. The lattermoves down vertically and presents the line to the casting mechanism O,&c. After the linotype has been cast the transporter moves upwardvertically beyond the level from which it started downward and standsstill, while a second lineshifter S draws the said line out of it. Thisshifting of the matrix-line out of the elevator is the first step towardthe distribution of the matrices and their restoration to the magazine,and therefore the lineshifting devices which remove the matrices afteruse may be considered a part of the distributing mech anism. Thetransporter N then moves downward to aline itself with thefirst-mentioned shifter L L; After the second-1nentioned line-shifter Shas drawn the composed line out of the transporter N the distributertakes the matrices out of the line and the spacebar grabber it draws thespace-bars into the space-bar magazine. None of the above parts form anypart of the present invention, and for that reason they are not includedin the accompanying drawings.

The present invention consists in automatic means combined with themachine for controlling the action of the shifting devices, so that thematrix-line will remain in the transporter or elevator and be presenteda second time to the mold before the shifting and distributing devicesare permitted to act. In the preferred form shown in the drawings Icombine with one of the cams, making a revolution for each linotypecast, a projection, a toothed wheel actuated thereby, and a stop on saidwheel to lock the matrix-shifter and space-bar grabber in their idlepositions until a second linotype has-been cast from the one line ofmatrices, automatic means being provided for unlocking them at theproper time.

Referring to the accompanying drawings, Figure 1 is a plan looking atthe machine from the right hand; Fig. 2, a sectional elevation on theline 2 2 of Fig. 1, looking from the lefthand of the machine; Fig. 3, asectional elevation from the right-hand side of the machine on the line3 3 of Fig. 4; Fig. 4, a rear elevation, and Fig. 5 a development of thecam-boss and cam-surfaces for preventing the stoppage of the casting andejectin g mechanism. I

A A are parts of the machine-frame; a, the cam-shaft; a, an elbow-leverfulcrumed on the frame A; Z, a cam keyed on the shaft a and revolving inthe direction indicated by the arrow; Z the lever that works thefirstmentioned line-shifter; Z the shaft on which it is fulcrumed; 1,its actuating-spring; s, the lever that works the second-mentionedline-shifter; a rock-shaft serving as its fulcrum; an arm fast to it; 8a connection from it to the lever s to hold the latter to the lever s;s, the fulcrum of the lever 8 s", the lever that works the space-bar thestud 9.

grabber; 8 the spring that returns the two levers 5' a continuation ofthe lever s on the opposite side of the fulcrum s and s a cam fast onthe shaft a to actuate the levers s and s by engaging anantifrictionroller on the end of the continuation All the parts justdescribed are substantially as described in the above-mentioned PatentNo. 436,532, and are marked with the same reference letters and figuresto facilitate identification of them.

1 is the above-mentioned projection. It is made fast to the periphery ofthe cam Z, from which it projects radially.

2 is a toothed wheel capable of a sliding motion along the shaft 3, butincapable of turning independently of the latter. This shaft is parallelwith the shaft a and turns in fixed bearings 4 4.

5 5 5 5 are stops symmetrically arranged on a boss 6, fast on the shaft3 and having as many notches 7 between them.

Sis a stud fast to the boss of the continuation 8 and therefore movingor standing still with the lever s. The wheel 2 presents either a stop 5or a notch 7 in the path of the stud 8. Each of the stops 5 is strongenough to stop the lever s and each of the notches 7 large enough to letthe stud 8 swing through it.

9 is a pin projecting for the same distance from opposite sides of theshaft 3 and fast to it.

10 is a groove in the left face of the wheel 2. It is long enough andwide enough to stand over the pin 9, but shallow enough to prevent thewheel 2 sliding along the shaft 3 to the left far enough to carry itpast the path of the projection 1.

11 is a second groove in the same face of the wheel 2, but at rightangles with the groove 10. It is deep enough for the wheel 2 to be movedalong the shaft 3 to the left far enough to carry it past the path ofthe projection 1.

12 is a spring on the shaft 3, resilient between the right-hand bearing4 and the boss of the wheel 2 to keep the latter engaged with Theengagement of the latter in either of the to the shaft 13 13 are equaland equidistant cam-surfaces carried by a boss 14, fast on the shaft 3.

Reference to the above-mentioned patent will show that a linotype iscast at each revolution of the cam-shaft a and that the latter is thenautomatically stopped by the lever a 15 is a wedge-shaped projectionfast on the lever a", so positioned thereon as to stand in the path ofone of the cam-surfaces 13.

16 16 are notches, one following each camsurface, to lock the lever a byreceiving the edge of the projection 15.

The invention acts as follows after the wheel 2 has been set with theshallow groove 10 over the pin 9 by hand: As the projection 1 comesround it engages the particular tooth of the wheel 2 that is standing inits path at grooves 10 or 11 looks the wheelthe moment and turns itabout its axis for the distance of one tooth, thereby presenting a stop5 in the path that the stud 8 will take the next time the lever s isrocked. The cam 1 then proceeds on its revolution,- as heretofore. Whenthe transporter reaches the top of its stroke, the line of matrices andspace-bars is not drawn out of it, but is taken back byit and then tothe casting mechanism as if it were a fresh one from the first-mentioned line-shifter. Fracture of any part of the mechanism connectedwith the levers s s is prevented by the compensating device heretoforepresent in it, so that a special one is not required by the presentinvention. When the projection 1 locked the lever s in the way justdescribed, it made the particular cam-surface. 13 that was then incontact with the projection 15 rock the lever (0 This contact beginsbetween the middle of the said cam-surface and the edge of theprojection, as shown in Fig. 4, and continues'until the lever c has beenrocked far enough to the left to prevent it acting, at which moment therespective notch 16 stands opposite the edge of the projection 15 andreceives it, thereby locking the lever Ct in its inoperative position.The edge of the projection 15 is forced into the notch 16 by a spring.(Not included in the drawings.) As long as the lever a remains in theposition just described it will fail to automatically stop the shaft (1at the end of the revolution of the latter, so that it will start on asecond one and during that second revolution the duplicate linotype willbe cast. Each second contact of the projection 1 with the wheel 2 willmake the latter present a notch 7 in the path of the stud 8, so leavingthe levers s s free to act normally, and will also make the shaft 3disengage the cam-notch 16 from the projection 15, which is immediatelyforced up to the next camsurface 13, thereby allowing the lever a toswing back into its operative position. I believe myself to be the firstto provide a mechanism through which the retention of the line ofmatrices in operative position is effected and its distributionprevented until the line has been used for the production of twoduplicate linotypes. In other words, I believe myself to be the first toincorporate in a linotype-machine automatically-acting mechanism causingtwo .linotypes to be cast in succession from one line of matrices, andthereafter causing automatically the distribution of the matrices. Itwill be manifest to the skilled mechanic that the details ofconstruction can be variously modified, the only essential requirementbeing that the stop devices or devices to control the action of thedistributing mechanism should be connected with and driven from asuitable part of the machine and that they shall act automatically firstto arrest the distribution and thereafter to permit the distributionafter the sec 7 0nd linotype has been cast.

That I claim isp 1. In combination with a linotype-machine, an automaticsupplementary mechanism, acting to prevent the shifting of eachmatrixline until a second linotype has been cast therefrom, wherebylinotypes may be produced in duplicate.

2. In a linotype-machine, and in combination with a shaft from which thecasting and matrix-distributing mechanism are driven, a supplementalmechanism, also driven from said shaft and constructed to prevent everyalternate action of the matrix-distributing devices, whereby each lineof matrices is left in posit-ion for the casting of a second linotypetherefrom.

3. In a linotype-machine having matrixdirtributing mechanism arranged tooperate normally after each casting operation, a supplementalautomatically-operating mechanism, to prevent every alternate action ofthe line-shifting mechanism; whereby the machine may be caused toautomatically produce linotypes in duplicate.

4. In a linotype-machine, a supplemental mechanism adapted to be throwninto and out of action at will, and acting when in use to cause theretention of each matrix-line in operative position until a secondlinotype has .been cast therefrom and thereafter automatically releasingthe distributing mechanism.

5. In a linotype-machine'and in combination with the shifting-levers andactuating mechanism therefor, the rotary notched stop driven by themachine and acting to hold the levers out of action periodically asdescribed, whereby the casting of duplicate linotypes from eachmatrix-line will be effected.

6. In a linotype-machine, automatically-ac; I tuated mechanism,restraining thedistribution of the matrix-line until a second linotypehas been cast therefrom, and thereafter permitting the action of thedistributing mechanism.

7. In a Mergenthalerlinotype-machine, the combination of the lineshifterlever s, the rotatable notched stop to arrest the action of said lever,and driving connections, substantially as shown, for imparting anintermittin g rotation to said stop.

8. In a Mergenthaler linotype-machine, the combination of the rotarycam, provided with projection 1, the notched wheel 2, driven thereby,the notched stop 5, and the shifterlever, having a projection 8 toencounter said stop, said parts timed and arranged as de scribed to holdthe shifter-lever at rest until the machine has completed two cycles andproduced two linotypes from the one line of matrices.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
